The generously sized planar driver allows you to indulge in an expansive soundstage and powerful, energetic bass.\u003c\/p\u003e\n\u003cp\u003e*Unlike conventional dynamic or balanced armature drivers, the planar driver is powered by an electromagnetic force acting across the entire, lightweight and thin diaphragm surface. This ensures uniform force is applied across the entire diaphragm, virtually eliminating the sectional distortion common in dynamic drivers. The result is low distortion, superb transient performance, and a vast soundstage. While the complex manufacturing involved often makes planar technology more expensive, the sonic benefits are clear.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"Taken apart ear cup of the JT7\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/11564443_crop.jpg?v=1770066391\"\u003e\u003c\/p\u003e\n\u003ch2\u003e3um ultra-thin diaphragm\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eLight and agile movement For brilliant treble\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFor a planar diaphragm to deliver its signature quick vibration and sensitive response, it must be exceptionally thin.

These textures, similar to the surround ring on a dynamic driver, increase the diaphragm's elasticity. Compared to typical planar drivers, this innovation allows for precise control over internal stress, allowing the driver to move even more freely without added distortion.
